URINAL.

Specification of Letters Patent.

Patented Feb. 27, 1912.

Application filed January 10, 1910. Serial No. 537,231.

To all whom it may concern:

Be it known that I, JOHN A. DAVIDSON, a citizen of the United States,residing at Chicago, in the county of Cook and State of Illinois, haveinvented certain new and useful Improvements in Urinals, of which thefollowing is a specification.

The present invention relates to a urinal of that class in which thereis one or more stalls each complete in itself, its several integrantparts being molded integrally of suitable plastic material so as topresent a continuous unbroken inner surface without any seams, joints,interstices or rough places which can afford places for the lodgment ofimpure matter. Such stalls are sometimes used singly and sometimes inranges of any desired number. Each stall consists of a base or receptorprovided with a suitable Waste opening, a back wall and two side wallssupported by the bottom, and a topwall supported by the back and thesidewalls and forming a hood, but this top-wall is usually cut away orrecessed more or less at its front side in order to make way for thebody and is sometimes omitted altogether. The present invention is not,however, concerned with details in the construction of the stallexcepting that it is designed and intended for use only in connectionwith those stalls which are in the nature of individual structures orentities having at least some of their several integrant partssay theirbase or receptor, back and side walls molded integrally so as to beunited wit-hout seams, joints or interstices.

The invention relates more particularly to the means forand manner ofsetting the stalls, whet-her used singly or in ranges, so that thestructure, when completed, will be strong, durable, but little liable todamage or injury due to irregularities in or unequal settling ofadjacent parts or objects,and so that the completed structure will havea neat, finished appearance susceptible of any ornamentation that may bedesired, and

withal sanitary, having but few joints, crevices or interstices thatcanaiford lodgment for foreign substances.

To these ends the invention consists in the features of novelty that arehereinafter described with reference'to the accompanying drawing, whichis made a part of this specification and in which:

Figures 1 and 2 are, respectively, a plan elevation and a front view ofa urinal comprising two stalls embodying the invention. Figs. 3, 4 and 5are vertical sections on the lines 33 and t4, and 5-5, respectively,looking in the direction of the arrows, intermediate horizontal portionsof F ig'. 3 being broken away. Fig. 6 is a diagrammatic view, on asmaller scale of a slab of modified form.

Each of the stalls comprises a base or receptor, A, havingthrough it asuitable waste opening, a, a back-wall, A two sidewalls, A and a top, Aa suitable opening, a, for the admission of a water supply pipe beingformed through the top or any other desired part of the stall. Asbeforestated the stall,

molded integrally, of clay or other plastic material and then baked sothat it is without seams, joints or interstices and is in and of itself,an individual entity. Its interior surface is preferably smooth andshaped upon curved lines without reentrant angles. Its exterior may varyin shape, more or less, but the invention is more particularly adaptedto and intended for use 'in connection with stalls the outer surfaces ofthe side-walls of which are flat. As shown in the drawings the top isrecessed or cut away somewhat, and this recessing or cutting away may becarried to any extent, or the top may be altogether omitted, withoutdeparting from the spirit of the invention.

VVhen'only a single stall is used two slabs, B and B, are placed againstits opposite sides respectively, said'slabs being rightand-left andhereinafter called terminal slabs. These slabs have flanges, b, b, whichoverhang and conform to the contour of the top and front of the sides,which, in the illustration given are straight, and at right angles toeach other, but this is a matter of taste which is left to the choice ofthe designer. The slabs and flanges are integral and preferably moldedof .clay or other plastic material and baked. Themain or body portionsof the slabs, namely the portions bounded by the flanges, may, ifdesired, be exactly conterminous with the sides of the stall but thiswould be open to the objection that great nicety would be required informing and proportioning all of the parts, including theroughing-inwork, and, of course, the greater the nicety required, the greater willbe the expense. In order to obviate this requirement for" such nicety'the slabs are preferably somewhat greater in depth, or horizontal extentfrom front to back, than are the sides of stalls so that in order toproduce a finished and workmanlike appearance it is necessary to finishonly the rear edge of the. slab so that itwill conform tothe surfaceagainst which it is placed while the back surface of the stall may befinished with less regard for accuracy. When this method is followed aspace of greater or less width will occur be tween the wall and thestall at the top thereof and this space may be closed and a finishedappearance produced by the use of a coping or strip of molding, C, soplaced that its front edge rests upon and is supported by the back ofthe stall. while its ends rest upon and are supported by the flanges ofthe slabs. These flanges and also the coping strips may be of anydesired ornamental shape. In. the drawing the coping strips and'thehorizontal portions of the flanges are curved or rounded as are also thelower portions of the vertical portions of the flanges while the upperportions of said vertical portions are of ogee shape. This is desirablein that the forwardly projecting portion forms a shield. When the stalland slabs are in place they are secured together by any suitable cementapplied to their opposing surfaces wherever desirable or necessary.

Where two or more stalls are used a slab, D, hereinafter called anintermediate slab, is arranged between each two adjacent stalls and eachof these intermediate slabs has flanges, d and d, projecting from itsopposite faces and overhanging the top and front of adjacent sides ofadjacent stalls respectively. The intermediate slab differs from theterminal slabs in that the area of its rear edge which is adapted tocontact with the adjacent wall or other object is reduced to a minimum.That is to say the rear edges of the terminal slabs are perfectlystraight from top to bottom as shown at B in Fig. 4:, while the area ofthe rear edge of the intermediate slab, which is adapted to contact withthe adjacent wall, is reduced to a minimum as shown at D in the samefigure. I

The order in which the parts are assembled is immaterial and may bevaried at will and a suitable order appropriate to individual cases willreadily suggest itself to any one'skilled in the art. It is, of course,the intention that the structure shall have a finished and workmanlikeappearance and it is the object of the invention to provide means bywhich this can be accomplished without the expenditure of much time andlabor. This may be accomplished by following the foregoing specificationand in addition to this the completed structure has the advantage ofstrength, durability, and a minimum liability to injury or breakage dueto the un equal settling of floors, foundations or other supports,especially where a number of stalls are assembled in a single range.

lVhen constructed and assembled as above described each stall 1scomparatively free and independent of the others so that if one settlesvit doesinot of necessity produce a break strain upon another and,furthermore, if one settles to the extent of opening up a joint or seambetween it and the adjacent part the joint remains concealed by theflanges of the slabs. Furthermore contacting faces of the ends of thestall and the slabs are complementary to each other so that they servethe double purpose of giving the structure end-wise solidity andmaterially lessening time and labor spent in setting them.

The parts carrying the flanges have, in the foregoing description beentermed slabs and they areshown as being practically conterminous withthe sides. This is advantageous because, by reason of the extent of themain portions of the slabstheir liability to warp while being baked islessened and furthermore they add strength to the structure inproportion to their extent. But in addition to this they have a functionpeculiar to the flanges only and so far as the performance of thisfunction is concerned they may be reduced to a minimum as indicated inFig. 6. In all instances however the flanges considered alone areofthenature of beads or moldings which cover and break the jointsbetween the adjacent surfaces of the stalls and in furtherance of theperformance of thisfunction the so called slabs, of whatever extent,serve as anchors for holding the beads or flanges in place.

What I claim as new and desire to secure by Letters Patent is:

1. A urinal having a stall, the back and sides of which are integral,right-and-left terminal slabs lying against and covering the sides ofthe stall, said slabs having flanges overhanging the top and front ofsaid sides, and a coping strip supported at its ends by the slabs and atits front side by the stall.

2. A urinal having a stall, the back and sides of which are integral,right-and-left terminal slabs lying against and covering the sides ofthe stall, said slabs being of greater depth than said sides, and saidslabs having flanges overhanging the top and front of said sides andcoping strips supranged side by side, the back and sides of each stallbeing integral, right-and-left terminal slabslying against and coveringthe outer sides of the terminal stalls of the range, said slabs havingflanges overhanging the tops and fronts of said outer sides of theterminal stalls, intermediate slabs arranged between the adjacent sidesof adjacent stalls, said intermediate slabs having flanges projecting inopposite directions and overhanging the top and fronts of said adjacentsides of adjacent stalls and coping strips supported at their ends bythe slabs and at their front sides by the stalls.

4. A urinal having a stall, the base or receptor, back and sides ofwhich are integral, slabs lying against the sides of the stall, saidslabs having flanges overhanging the top and front of said sides, and acoping strip supported at its ends by the front side by the. stall.

5. A urinal having a stall the base, or receptor, back and sides ofWhich are integral, slabs lying against the sides of the stall, saidslabs being of greater depth than said sides, and said slabs havingflanges overhanging the top and front of said sides, and a coping slabs,and at its strip supported at its ends by the slabs and at its frontside by the stall.
